Fishwiring is when you run a bolt leader, which is a long wire that on one end you can thread a bolt (it looks like spring), through the hole the bolt needs to go in, and out through a larger access hole. You then put on a spacer block or washer, then thread on the bolt and pull them back through the first hole.

Reverse fishwiring is when you put on the spacer block or washer, thread on the bolt, then shove them into the same hole they will need to come out of. Then you pull the fishwire back out so the bolt and washer or spacer seat properly.

I have included a video showing fishwiring and an FAQ with a section on fishwiring for you.

If you plan on doing some towing I recommend the etrailer ball mount kit # 989900 which comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a storage bag. For trailer wiring use # C56040.
